Now I see the source of my error: I quoted the data file name! Removing the quotation marks produces the plots.
Thanks to A.K. and Dennis Murphy I understand how to plot the data in these data sets. However, I am not getting the colors within the plot to match those in the key despite reading about using color pallettes and experimenting with pallettes and various numbers of colors. Since I don't see what I'm doing incorrectly I'd appreciate having someone point this out to me. Data set:
structure(list(sampdate = structure(c(11156, 11156, 11156, 11156, 11156, 12241, 12241, 12241, 12241, 12241, 12977, 12977, 12977, 12977, 12977, 13327, 13327, 13327, 13327, 13327, 14866, 14866, 14866, 14866, 14866, 14866, 14866, 15168, 15168, 15168, 15168, 15168, 15168, 15170, 15170, 15170, 15170, 15170, 15170, 15170, 15532, 15532, 15532, 15532, 15532, 15532), class = "Date"), func_feed_grp = structure(c(1L, 2L, 3L, 6L, 7L, 1L, 2L, 3L, 6L, 7L, 1L, 2L, 3L, 6L, 7L, 1L, 2L, 3L, 6L, 7L, 1L, 2L, 3L, 4L, 5L, 6L, 7L, 1L, 2L, 3L, 4L, 5L, 6L, 1L, 2L, 3L, 4L, 5L, 6L, 7L, 1L, 2L, 3L, 4L, 6L, 7L), .Label = c(" Filterer ", " Gatherer ", " Grazer ", " Omnivore ", " Parasite ", " Predator ", " Shredder "), class = "factor"), pct = c(0.0351, 0.7054, 0.0442, 0.1078, 0.1074, 0.157, 0.7039, 0.0023, 0.0456, 0.0912, 0.0293, 0.6634, 0.0055, 0.0552, 0.2466, 0.0414, 0.4776, 0.1033, 0.2012, 0.1765, 0.0811, 0.5785, 0.0284, 0.0131, 0.0018, 0.0736, 0.2234, 0.0041, 0.9011, 0.0563, 0.01, 0.0037, 0.0247, 0.0385, 0.8469, 0.0147, 5e-04, 0.0197, 0.0688, 0.0109, 0.1275, 0.503, 0.0257, 8e-04, 0.1464, 0.1966)), .Names = c("sampdate", "func_feed_grp", "pct"), row.names = c(NA, -46L), class = "data.frame")dput(bdf)
The command I'm using to plot this data frame: xyplot(pct ~ sampdate, data = bdf, groups = func_feed_grp, type = 'l', col = rainbow(8), key = simpleKey(text = levels(bdf$func_feed_grp), space = 'right')) I've used rainbow(6) through rainbow(12) and cannont get it correct. A sample plot is attached. Notice for the left-most points (year 2000) there are 5 functional feeding groups in the data: gatherers (approximately 70 percent), predators and shredders (approximately 10 percent each), grazers and scrapers (approximately 4 percent each). According to the key parasites are approximately 70 percent of those data and gatherers approximately 10 percent. That's not correct. Rich
